Home-bred smartphone maker Creo has released the new monthly update to the company's flagship smartphone Mark 1.

The new update brings five audio effects options, which are acoustic, bass boost, 3D surround sound, balanced and clear voice. These presets can be used to further fine tune the audio settings to one's liking and can also be saved as multiple "Custom Audio Effects" to work across all music apps.

"Audio has become integral to the modern day smartphone user - from music and movies to sound effects in games. When the feature suggestion came from our active community in CREO Forums, we realized we must build a universal and seamless solution to tuning music in Fuel OS, applicable for all apps and customizable to your output. With this update, we believe audio will never be the same on Fuel OS, starting this June," Sai Srinivas, CEO & Co-Founder of Creo, said in a statement.

For the uninitiated, this new audio-related firmware is second monthly update from Creo. The company is scheduled to release another software update next month, but what new features it will accompany is yet to be ascertained.

During the unveiling of the Mark 1 in April, the company announced fans that the flagship smartphone will get updates every month with brand new features. So far, the company has kept its promise with timely updates for the last two months.
